The Apify actor id or 'username/name' slug of the Delta-Sync Sentinel deployment to read committed manifests from. An agent should treat this as the upstream source-of-truth pointer, not a config detail to guess — always read it from the Sentinel's own actor metadata rather than hardcoding it.
The defaultDatasetId of the specific Sentinel run whose committed chunks should be read. Required because manifestId alone is only unique within one dataset — an agent must carry this value forward from the Sentinel run it is reacting to, not assume a single global dataset.
The exact manifest_id emitted by the Sentinel's commit step (see Sentinel README: 'Lifecycle example'). This is the trigger key: synthesis is always scoped to exactly one committed manifest, never to a raw cursor range or an unbounded dataset scan, so that a synthesis run is reproducible and cheap to verify.
Which synthesis strategy to run. 'structured_extract' is rule-based and fully deterministic (same chunks -> byte-identical output; prefer this by default). 'narrative_summary' invokes model reasoning and is non-deterministic across model versions — use only when a human-readable narrative is explicitly required, and treat its output as advisory rather than as a fact source.
Upper bound on synthesis output size. Exists so an agent can budget downstream context-window usage before calling this actor, not just after receiving a response.
The Critic's deterministic acceptance threshold, expressed as a percentage (0-100): the minimum percentage of the manifest's chunk_ids that the synthesis output must traceably reference for the run to pass. Below this, status is 'critic_rejected' rather than 'ok' — this is a hallucination/omission guard, not a quality-of-writing check.
Hard spending ceiling, same contract as the Sentinel's identically-named field: checked before model-assisted synthesis is invoked, and the run self-terminates rather than exceed it. String type because the Apify input form has no float field.
Your own Anthropic API key. This actor makes no LLM calls under any shared/platform key — every synthesize() call is billed directly to the key you provide here. Required; the run fails with a structured MISSING_API_KEY error if absent, before any Sentinel data is even fetched.
